The median is the middle number when the numbers are put in ascending order (lowest to highest)
1, 2, 3, 4, 4, 7
The middle numbers are 3 and 4. The number between 3 and 4 is thus the median - this number is 3.5
Answer:13.5 inches
Step-by-step explanation:
Given diagonal as 15.6inches
Width is unknown
Height is 7.8 inches
From the diagram attached it forms a right angle solved using Pythagoras theorem
Ie
15.6^2=width^2+7.8^2
Width= ✓(15.6^2-7.8^2)=13.5inches
Answer:
a) Эx ∈ R ⊇ x³ = 2
b) ∀x ∈ R, x² ≥ 0
c) Эx ∈ R ⊇ x³ = x
d) ∀x ∈ R, x ≤ x²
Step-by-step explanation:
Given the data in the question;
let us first go through some symbols and their possible meanings;
Э ⇒ there exists
∀ ⇒ for all
∈ ⇒ belongs to or set membership or element of the set
⊇ ⇒ such that
now;
a) There is a number whose cube is equal to 2
let x represent the number; so
Эx ∈ R ⊇ x³ = 2
b) The square of every number is at least 0
x² ≥ 0, ∀x ∈ R
∀x ∈ R, x² ≥ 0
c) There is a number that is equal to its square
Эx ∈ R ⊇ x³ = x
d) Every number is less than or equal to its square.
x ≤ x², ∀x ∈ R
∀x ∈ R, x ≤ x²
We are given:
First, let's simplify that fraction. We know that 5 goes into 25 5 times. So we can rewrite the equation as:
Combine like terms.
Divide both sides by -2 to get x all by itself.
Simplify
Hope this helps!
